FILLING-REPLENISHING LOOM.

Application filed May 25, 1914.

To all whom it may concern:

Be it known that I, ALoNzo E. Rnoanns, a citizen of the United States, residing at l-lopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Filling-Replenishing Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to a means for preventing the operation of the filling replenishing mechanism in an automatic loom upon the failure of the filling feeder properly to position a filling carrier for transfer after the indication of entire or partial eX- haustion in the running shuttle, and the object is to provide a simple and efficient means for securing this result, particularly by or through the restraining of the operation of the usual shuttle feeler when the filling feeder is improperly positioned.

The nature of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

The drawings show so much of an ordinary automatic filling replenishing loom together with the parts constituting a preferred form of this invention as is necessary to an understanding of the invention.

in the drawings, Figure l is an end elevation and partial transverse section of a sufficient portion of an automatic filling replenishing loom of the Northrop type with the parts involved in this invention applied thereto; Fig. 2 is a detail in cross-section showing the movable catch for indicating the correct position of the feeder.

The construction of the loom illustrated and to which a preferred form of the invention is shown as applied is of the well known Northrop type, and in connection therewith is shown a well known type of shuttle feeler and shuttle feeler thread cutter mechanism similar in general to that shown in the patent to C. H. Draper No. 683,423 granted September 24., 1901, and in view of the well known character of these mechanisms it will be unnecessary here to describe anything more than those parts directly concerned with the present invention.

The breast beam of the loom is indicated at 1 and has fixedly mounted thereon the Specification of Letters Patent.

usual filling feeder which comprises two disks or plates to receive, hold and position the spare filling carriers. Une of these disks or plates is shown at The hopper stand 3 with its integral casing 4 inclosing the disk 2 toward the center of the loom is secured in the usual manner to the breast beam.

The filling carriers or bobbins 5 are as usual held by their butts and tips by and between the two disks of the hopper or feeder in a circularly arranged series, the seats for the butts being shown at 6 in the disk 2. The filling carriers are brought one by one into position for transfer from the hopper or feeder to the running shuttle by the usual mechanism, such, for example, as illustrated and described in the .patent to Stimpson & Southwick No. 823,6-l4 granted June 19, 1906. The filling replenishing mechanism also comprises a transferrer 7 pivotally mounted at 8 on the hopper stand and operating when depressed or moved downward to transfer a filling carrier from the hopper to the shuttle. A notched dog 9 is pivoted at 10 to the depending arm of the transferrer and upon the call for filling replenishment is swung upwardly into the path of a bunter 11 carrier by the lay 12, all in a manner well known and familiar in this type of automatic filling replenishing looms.

The shuttle feeler l8 rocks and slides on the hub 1e and is provided with the usual. thread clamping and parting means 15, the details of which are not involved in connection with this invention. T he shuttle feeler is provided with a usual projecting pin 16 projecting from the shank of the feeler, and this pin is engaged by the arm 17 connected to the usual rock shaft 18, and. is held against the pin by the spring 19. The dog 9 is operated from the shuttle feeler by means of the cam slotted arm 20 bolted at 21 to the shuttle feeler. The construction and operation of this mechanism is well known and familiar to those skilled in the art. In the operation of this type of loom when a replenishment of filling is called for the shaft 18 is rocked in the usual manner raising the arm 17 and allowing the shuttle feeler to swing toward the lay. If the shuttle is properly boxed the feeler will pass in front of the shuttle in the usual manner, the dog 9 will be brought into the path of the hunter 11, and the transferrer 7 will be operated in the usual manner to transfer the filling carrier, such as the bobbin 5 from the hopper into the shuttle therebeneath. If the shuttle be improperly boxed so that it is struck by the shuttle feeler, or if the shuttle feeler be restrained in its forward movement so as not to bring the dog 9 into the path of the hunter 11, transfer of the filling carrier from the hopper or feeder will not be effected.

The present invention is concerned as already stated with means to prevent the transfer of the filling carrier taking place when the filling carrier is improperly positioned by the feeder or hopper for transfer. As fully explained in the patent to F. G. & J. H. Cobb No. 780,266, granted January 17, 1905, should the hopper or feeder fail properly to present a filling carrier in accurate position for transfer, the transferrer upon the neXt operation of the replenishing mechanism would improperly engage the filling carrier and injure it or some of the adjacent mechanism. This undesirable result is prevented by the present invention, and this is done by restraining the movement of the shuttle feeler when the filling carrier is so improperly positioned.

In the construction illustrated the disk 2 in which the butts of the spare filling carriers are seated is provided with positioning seats one for each filling carrier, and having a definite position with respect to said filling carrier. Preferably these positioning seats are in direct alinement with the corresponding seats for the butts of the filling carrier, and are herein shown as beveled recesses 22 formed in the face of the disk 2 opposite the butt seats. A movable or yielding catch is provided on the hopper stand to cooperate with the positioning seats so that when a filling carrier is brought into proper position for transfer by the rotation of the hopper or feeder this catch will move or spring into the corresponding positioning seat, and until the catch is in the positioning seat the hopper or feeder will not be properly positioned.

In the construction illustrated the catch is shown as a stud 23 provided with a frustoconical head 24: and movably mounted in a hub 25 secured to or formed integral with the casing 4: of the hopper stand. A helical spring 26 surrounds the stud 23 within the hub 25 and acts to move the catch yieldingly in the direction of the hopper or feeder while a pair of lock nuts 27 serve to adjust the extent of movement of thecatch. The fact that the catch is conical in shape at the end and the positioning seats are correspondingly beveled aids the catch in finding the positioning seat and also serves to some extent to position the filling feeder as the catch springs into place.

The shuttle feeler 13 already described is provided with a lug or projection 28 projecting upwardly therefrom and carried by the shuttle feeler in its movement into the path of the stud 23 of the catch when the catch is in its retracted or unseated position, but the stud 23 is of such length that when the catch is seated in a positioning seat the lug 28 will pass by the end of the stud 23. It will thus be seen that if the filling feeder is improperly positioned for transfer of the filling carrier the stud 23 will be struck by the projection 28, and the movement of the shuttle feeler restrained, the dog 9 will not be lifted into the path of the hunter 11, and transfer will not be effected. The invention thus presents a means rendered active by the hopper or feeder itself when improperly positioned for the transfer of a filling carrier to restrain the movement of the shuttle feeler, and thus to prevent the operation of the transferrer.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a loom, automatic filling replenishing mechanism including an intermittingly movable feeder to contain a plurality of filling carriers, a transferrer to transfer a filling carrier therefrom, a shuttle feeler and means to prevent the operation of the transferrer when the movement of the shuttle feeler is restrained, and means rendered active by the feeder itself when improperly positioned for the transfer of a filling carrier to restrain the movement of the shuttle feeler and thus to prevent the operation of the transferred.
